The imager is capable of decoding multi-row OCR text. Note: Reading rows longer than sixteen
characters is not recommended.
Consider the following example. This example shows serial commands as they would be entered
using Quick*View.
Example: You need to read multiple rows of OCR-A data as shown below:
12345678
ABCDEFGH
First, enable the OCR-A font. To read the first row of OCR data, you would program the following
template:
OCRTMP"dddddddd".
This template is the default OCR template. If you wanted to read the second line of data, you
would use the following template:
OCRTMP"llllllll".
To read both lines of OCR at one time, use the variable
r to indicate the start of a new row. All the
other templating variables for the individual rows work the same as previously described. For
instance, in the above example, you would use the following template to read both rows:
OCRTMP"ddddddddrllllllll".
To
read the three rows below, you would use the template command
"OCRTMP"ddddddddrllllllllrlllldddd".
12345678
ABCDEFGH
ABCD1234.
OCR Check Character
You may want to print and verify a check character in order to enhance the security of your OCR
application. The imager can be programmed for almost any type of check character. A number of
presets are provided for common check character uses (e.g., modulo 10 and modulo 36).
Scan the
OCR Modulo 10 or OCR Modulo 36 Check Character barcode to specify the type of
check character used in the OCR strings you‟re scanning. The imager will then only read OCR
character strings with a valid check character. The imager transmits the OCR data without the
check character data. You must specify the location of the check character in the template with a
c .
Example: You need to read any combination of seven digits, with a modulo 10 check character in
the eighth position. The template would be:
dddddddc
